Storage container

ABSTRACT

A storage container includes a base and a plurality of walls extending upwardly from the base. At least one of the walls includes a plurality of projections on its exterior at different heights. The interior of the wall includes a plurality of channels into which the projections of a like container would be slidably received when the empty containers are nested. A plurality of supports are pivotably connected to the container and can be selectably pivoted to block selected ones of the plurality of channels such that the projections are supported on the supports and do not enter the channels, thereby supporting the upper container at a selected height.

RELATED APPLICATIONS

This application is a continuation of application Ser. No. 11/073,336,filed on Mar. 4, 2005.

BACKGROUND

Portable storage containers that both stack and nest with similarcontainers are commonly used in industry for transporting and storinggoods. Nesting is typically achieved with an empty container receives alike container therein such that there is overlap between the walls andcontainer. On the other hand, the stacking feature is typically usedwhen an occupied container has a like container supported thereon, suchthat there is relatively little or no overlap between the walls of thecontainer, and the goods contained in the lower container are preferablynot contacted or damaged by the upper container.

Many containers include bail members to achieve this stacking feature.Bail members are typically slidably and pivotally connected to oppositewalls. The bail members can be positioned out of the way for purposes ofnesting, and can be moved to one or more stacking positions (i.e.,vertically aligned with the floor) to permit another container to bestacked thereon.

SUMMARY

A storage container according to the present disclosure includes a base,a pair of opposed end walls extending upwardly from the base and a pairof opposed side walls extending upwardly from the base. A support systemis mounted proximate each end wall. Each support system includes aplurality of supports pivotably connected to the end wall. Each end wallfurther includes a plurality of projections from the exterior of the endwall. The projections are formed at different heights from the base inpairs. For example, in the embodiment described, there are three pair ofprojections on each end wall, the two projections within each pair areat the same height and each pair of projections is at a differentheight. Each projection forms corresponding vertically-extending channelon the interior of the end wall, such that the projections of onecontainer would be aligned and would be slidably received within thechannels of a similar container into which it is nested.

When pivoted inwardly to a support position, each of the supportsselectably blocks one pair of the channels such that the projections ofthe upper container would not be received within the blocked channel,but would be supported upon the support. By selectively blockingdifferent channels, and thereby providing support to projections ofdifferent heights, the upper container is supported at varying heightsrelative to the base of the lower container.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

A storage container 10 according to the present disclosure is shown inFIG. 1. The storage container 10 generally includes a floor or base 12,a pair of side walls 14 and a pair of end walls 16 extending upwardlyfrom a periphery of the base 12. A support system 18 is mounted to thecontainer 10 proximate each end wall 16. In the embodiment shown, thesupport system 18 is mounted to an upper edge of the end wall 16. Thesupport system 18 includes a first support 20 hingeably mounted to theend wall 16. A second support 22 and a third support 24 are eachhingeably mounted to the end wall 16. The first, second and thirdsupports 20, 22 and 24 are each independently pivotable relative to oneanother and relative to the end wall 16 about a common axis 26 adjacentan outer edge of an upper surface 28 of the end wall 16.

Each end wall 16 includes an exterior surface 30 and an interior surface32. A horizontal lip or flange 34 protrudes outwardly from the exterior30 of each end wall 16. The interior 32 of each end wall 16 includes apair of vertically extending first channels 40 a pair of verticallyextending second channels 44 outward of the first channels 40 and a pairof vertically extending third channels 48 outward of the second channels44. The channels 40, 44, 48 open upwardly and inwardly. The channels 40,44, 48 define alternate first, second and third columns 41, 45, 49 thatextend to the upper surface 28 of the end wall 16. Each channel 40, 44,48 also forms a corresponding first, second and third projection 42, 46,50, respectively, on the exterior surface 30 of the end wall 16. A lowerend of each projection 42, 46, 50 forms an interlocking member 43, 47,51, respectively. The lower ends of the first projections 42 are at afirst height above a plane containing the base 12. The lower ends of thesecond projections 44 are at a second height relative to the base 12,the second height being less than the first height. The lower ends ofthe third projections 48 are at a third height relative to the base 12,the third height less than the second height. Each side wall 14 alsoincludes a horizontal lip or flange 56 and further includes an openingto form a handle 58.

As can be seen in FIG. 2, the first, second and third supports, 20, 22,24 are each pivotable relative to the container. Each support 20, 22, 24includes a pair of flaps 60 hingeably connected to the end wall 16 andconnected to one another by a beam 62. In FIG. 2, the first supports 20have been pivoted to a stack position. In the stack position, the flaps60 cover and block the first channels 40 while being supported on thefirst columns 41 and the upper surface 28 of end wall 16. Similarly, thesecond support 22 can be pivoted to a stacked position in which theflaps 60 would cover and block the second channels 44 and be supportedon the first and second columns 41, 45. Similarly, a third support 24can be pivoted to the stacked position where the flaps 60 would rest onthe second and third columns 45, 49 and hover and block the thirdchannels 48.

FIG. 3 illustrates the storage container 10 with the support system 18,including the first support 20, second support 22 and third support 24,in the open or nest position and with a like storage container 10′nested therein. The upper container 10′ and lower container 10 areidentical and corresponding components on the upper container 10′ willbe indicated with identical reference numerals appended with a primedesignation. Thus, descriptions of any components on the upper container10′ apply equally to the lower container 10 and vice versa. In thisposition, the empty containers 10, 10′ can be stored or shipped whileoccupying the least amount of space. Other similar containers can benested within the upper container 10′ and so on.

While nested, the flange 56′ of the upper container 10′ is supported onthe flange 56 of the lower container 10 and the flange 34′ of the uppercontainer 10′ is supported on the flange 34 of the lower container 10.As can be seen more clearly in FIG. 3, the upper surfaces of the columns41′, 45′ and 49′ each include a plurality of tenons 66′ which arepositioned to be received in mortises 68′ on the flaps 60′ of the first,second and third supports 20′, 22′, 24′.

In FIG. 4, the first supports 20, 20′ of the lower and upper containers10, 10′ have been pivoted to the stacked position in which the flaps 60,60′ cover the first channels 40, 40′ (FIG. 1). In this first stackposition, the flap 60 of the lower container 10 thus prevents the firstprojection 42′ of the upper container 10′ from entering the firstchannel 40. The first projection 42′ is supported on the flap 60 on thefirst support 20. The second and third projections 46′, 50′ of the uppercontainer 10′ are partially received within the second and thirdchannels 44, 48 of the lower container 10 respectively. The base 12′ ofthe upper container 10′ is supported at a first distance above the base12 of the lower container 10. The interlocking member 43′ of the firstsupport 42′ is received within a recess in the flap 60 of the firstsupport 20. Referring to the upper container 10′ where it can be seenmore clearly, the second support 22′ includes a tapered surface 72′ thatengages a tapered surface 74′ of the first support 20′ such that thesecond support 42′ cannot be pivoted to the stack position without alsopivoting the first support 20′ to the stack position. Similarly, thesecond support 22′ includes a tab 76′ that is engaged by the thirdsupport 24′, such that the third support 24′ cannot be pivoted to thestack position without also pivoting the second support 22′ (andtherefore the first support 20′) to the stack position.

In FIG. 5, the second supports 22, 22′ and the first supports 20, 20′are pivoted to the stack position. The flap 60 of the second support 22of the lower container 10 covers and blocks the second channel 44thereby preventing the second projection 46′ of the upper container 10′from entering the second channel 44 (FIG. 1). The flap 60 of the secondsupport 22 is supported on the first column 41 (FIG. 1) and the secondcolumn 45. The interlocking member 47′ of the second projection 46′ ofthe upper container 10′ is received within a recess of the flap 60 ofthe second support 22 of the lower container 10. The third projection50′ of the upper container 10′ is partially received within the thirdchannel 48 of the lower container 10. The base 12′ of the uppercontainer 10′ is supported at a second height above the base 12 of thelower container 10, the second height is greater than the first height.

FIG. 6 illustrates the support systems 18, 18′ in the third stackingposition, with the first, second and third supports 20, 20′, 22, 22′,24, 24′ in the stack position. In this position, the flap 60 of thethird support 24 of the lower container 10 covers and blocks the thirdchannel 48 (FIG. 1) and is supported on the second and third columns 45,49 (FIG. 1). The interlocking member 51′ of the third projection 50′ ofthe upper container 10′ is received in a recess of the flap 60. In thisposition, the base 12′ of the upper container 10′ is supported at athird, maximum distance above the base 12 of the lower container 10.This provides the maximum storage container in the lower container 10with the upper container 10′ stacked on it.

FIG. 7 is an end view of the storage container 10. As shown, the pair offirst projections 42 on end wall 16 are at the same height from the base12 and are laterally aligned with the flaps 60 of the first support 20.The pair of second projections 46 are at equal heights from the base 12,both lower than the first projections 42, and are laterally aligned withthe flaps 60 on the second support 22. The pair of second projections 46are laterally outward of the first projections 42. The pair of thirdprojections 50 are at equal heights from the base 12, both lower thanthe second projections 46, and are laterally aligned with the flaps 60on the third support 24. The pair of third projections 50 are laterallyoutward of the second projections 46.

FIG. 8 is a side view of the storage container 10. The third projections50 and the interlocking member 51 are shown.

FIG. 9 is a top view of the storage container 10, illustrating thecolumns 41, 45, 49 and the channels 40, 44, 48 formed on the interior 32of the end walls 16. FIG. 10 is a bottom view of the storage container10, illustrating the projections 42, 46, 50 and interlocking members 43,47, 51 formed on the exterior 30 of the end walls 16.

FIG. 11 is an end view of the storage container 10, with shading toindicate one potential useful color scheme. As shown, the first support20 is preferably a first color as are the first projections 42. Thesecond support 22 and the second projections 46 are a second color. Thethird support 24 and the third projections 50 are a third color. The endwall 16 (and the rest of the container 10) are preferably a fourthcolor. In this manner, it is easier for a user to select one of thesupports 20, 22, 24 by clearly recognizing the corresponding projection42, 46, 50. The supports 20, 22, 24 are molded separately from the endwall 16, and thus may be molded of a plastic of the appropriate color.The projections 42 may be painted, covered with stickers or molded of aplastic of the appropriate color using a multi-shot mold.

An end wall 114 of a storage container 110 according to a secondembodiment is shown in FIGS. 12-14. FIGS. 12-14 are top views of an endwall 114 that could be used in place of the end walls 14 in the storagecontainer 10 of FIGS. 1-11. Except as otherwise described, the storagecontainer 110 could be identical to the storage container 10 of thefirst embodiment except as otherwise described or shown below. The endwall 114 includes a first channel 140 and a second channel 144 on aninterior surface 132. The support system 118 includes a support 119 thatis slideable along the upper surface of the end wall 114, such that asupport surface or flap 60 can selectively cover and block neither ofthe channels 140, 144, the first channel 140 (FIG. 13) or the secondchannel 144 (FIG. 14). Additional channels (such as a third channel,like the first embodiment) could be added. Like the first embodiment,the end wall 114 of the storage container 110 includes a pair of firstchannels 140 (one shown) and a pair of second channels 144 (one shown)and the support 119 includes a pair of flaps 160 for covering the pairs.

In the description above and in the claims, the term “projection,” suchas the first, second and third projections 42, 46, 50, means any surfacethat protrudes laterally, or in a plane parallel to the base 12,relative to a surface above or below it vertically (i.e. perpendicularto the base 12). This is demonstrated by a third embodiment shown inFIGS. 15-16.

FIG. 15 illustrates a lower container 210′ and an upper container 210.The upper container includes a first projection 242 defined by a firstrecess 282 therebelow formed in the exterior surface 234 of the end wall214. Similarly, a second projection 242 is defined by a second recess284 therebelow.

By selectively pivoting a first support 220′ of the lower container 210′inwardly, the first projection 242 of the upper container 210 can besupported at a first height by the first support 220′ of the lowercontainer 210′, as shown in FIG. 16. The first recess 282 forms acorresponding first column 241 on a interior surface 232 of the storagecontainer 210.

Similarly, (although not illustrated) by selectively pivoting a secondsupport 222′ of the lower container 210′ inwardly, the second projection244 of the upper container 210 can be supported at a second height bythe second support 222′ of the lower container 210′. Additional supportsand projections could be used to provide different support heights, asin the first embodiment.
